daffodil (n.)

1540s, variant of Middle English affodill "asphodel" (c. 1400), from Medieval Latin affodillus, from Latin asphodelus, from Greek asphodelos, which is of unknown origin. The initial d- is perhaps from merging of the article in Dutch de affodil, the Netherlands being a source for bulbs. First reference to the flower we know by this name (Narcissus pseudo-Narcissus) is from 1590s. Lent-lily for "daffodil" is from 1827.
